Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments and drawings, but the present invention is not limited.

[0019] The phosphate mist purification system of the hot-dip galvanizing unit of the cold rolling plant provided by the present invention has a structure such as figure 1 Said: It is mainly composed of a horizontal purifier 8 and a ventilation system. The ventilation system is mainly composed of a centrifugal fan 15, an electric motor 13, an electric regulating valve 16, and a ventilation pipe. The inlet and outlet of the centrifugal fan 15 are each connected by a flexible connector 17 to the air supply pipe 11 and the exhaust pipe 18. Connected. At both ends of the horizontal purifier 8 are the air inlet pipe 6 and the air supply pipe 11 respectively. An electric regulating valve 16 is installed between the air supply pipe 11 and the inlet of the centrifugal fan 15.

[0020] The centrifugal fan 15 drives the impeller to rotate ...

Abstract

The invention provides a phosphate mist purification system of a hot galvanizing unit in a cold rolling mill, mainly consisting of a horizontal purifier (8) and a ventilation system, wherein, the ventilation system mainly consists of a centrifugal ventilator (15), a motor (13), an electric adjusting valve (16) and a ventilation pipeline, wherein, the inlet and the outlet of the centrifugal ventilator are respectively connected with a wind blasting pipe (11) and a wind outlet pipe (18) by a flexible connector (17); the electric adjusting valve is arranged between the wind blasting pipe and the inlet of the centrifugal ventilator; the horizontal purifier is arranged between a wind inlet pipe (6) and the wind blasting pipe (11). The purification system of the invention has the application in the small spangle processing phosphate mist purification of a hot galvanizing unit in a cold rolling mill, and has the advantages of high purification effect, causing no secondary pollution, convenient adjusting system wind quantity and wind pressure, reducing the resonance caused by that the vibration is transferred to system pipes and steel structures connected with the system pipes when the equipment system runs, compact structure, convenient operation, maintenance and troubleshooting, etc.

Description

Technical field [0001] The invention relates to a system for processing harmful gases, in particular to a phosphate mist purification system for a small spangle process in a hot-dip galvanizing unit of a cold rolling mill. Background technique [0002] In the phosphate mist purification system of the hot-dip galvanizing unit of the cold rolling mill, if the design of the key equipment-the purification device and the fan is unreasonable, it will cause problems for environmental protection and production. [0003] The phosphate mist purification system of the hot-dip galvanizing unit of Baosteel 2030 Cold Rolling Plant belongs to this category. After analysis, it was found that the purification device it introduced was an empty shell without filtering and fillers. There was only a section of spray water pipe that sprayed from top to bottom. The phosphate mist gas was not fully purified, so it was discharged and discharged. The gas was thrown into the sky outside the main factory bu...
